Abstract

New programs for fitting using an equivalent circuit model and data visualization of electrochemical impedance spectroscopy were developed using Python and its open-source libraries. Executable programs have a graphical user interface and can run on a Microsoft Windows operating system without utilizing other platform applications. Many practical functions were implemented, e.g., supporting various file formats, graphical support functions to obtain a good initial guess, display interactive three-dimensional plots of the spectrum, a modified logarithmic Hilbert integral transform test, display multiple spectra data, etc. The developed executable programs were released by free of charge for use under the MIT license.
